Single stage fuel filter with seal control air purge
摘要:
A fuel filter assembly (10) employs a base (20) which mounts a disposable filter cartridge (50). A pair of axial conduits (24,26) in the base (20) provide fluid communication between the base (20) and the cartridge (50). An axial sealing member (60) mounted in the cartridge (50) receives the axial conduits (24,26). An axial conduit (80) and preferably at least one baffle (88) positioned on the axial conduit outer surface within the cartridge (50) provide a flow path through the cartridge (50). An orifice (92) located in the cartridge axial conduit (80) provides a bleed vent which controls the size and flow rate of air bubbles in filtered fuel exiting the fuel filter. A flange-shaped end of the cartridge axial conduit (80) engages a ridge on the outside surface of the sealing member (60) to prevent the fuel flow from bypassing the baffle (88).
